no lift shift

Is there a way to set up your tune so you can shift at wot without the throttle blade closing when you hit the clutch?

Yes do you have a new motor ready to be installed when you miss a gear?

To funny!
We can also make it 100 throttle at start up. But even if we move the re limiter to 7000 and your valves will print smile faces on your piston. That will help mark the spot for your valve relief cuts for the new motor.

Yeah, it's called a 2-step, Lingenfelter and MSD make them. Alternatively, you can set up the tune with a lower rpm limit when in park/neutral. Stock, it's set too high (hence the need for a new engine if you miss a shift) LOL

Edit - and yes, you can have just spark control that versus spark and throttle and fuel.

Why would i need a new motor if i miss a gear? I thought thats what the rev limiter is for.

...there's this concept known as inertia...

Mass in motion tend to stay in motion...rev limiter have no brakes

Did you get your tune????

How do you like

Powershifting is a pretty standard technique when drag racing a manual. Don't want to miss a shift and over-rev and kiss your pistons? Learn how to shift properly.

I've used the Lingenfelter LNC-2000 alot, super easy to install. Owned an MSD that broke before ever using it on the strip. Implementing a 2-step in a tune is easy, but it's a little different than how the LNC does it and, of course, you need to know exactly how you're shifting as well, and if you change for some reason, say your at a track and you have traction issues and you're going to short shift 1-2, then you'll need to remember to lift on 1-2 if you intend to keep no-lift on 2-3, 3-4, etc.

Unless you're tuning with HP Tuners or EFI Live, I'd just get the LNC-2000 or the LNC-003.

Ok, let me see if I can get things straight here. When someone says miss a shift while power shifting and you will over rev the engine, they are talking about going into a lower gear right like shifting from 3rd, back to 2nd, instead of 4th or from 2nd to 1st right? Reason I ask is because you can still miss a shift and not go into any gear, the motor will still rev up, but the limiter should catch it right? Sorry, but I'm just trying to clarify and get things straight. Maybe powershifting is not a good idea on these cars. I've never tried to do it yet, I was just looking to see if its possible. The main issue I've read about was people saying you can't power shift these cars at all because even if you try, the throttle still closes during a shift, even when you have your foot to the floor.

Think about it: You've mentally committed your right foot to NOT move off the gas and you stab the clutch quickly while pulling the shifter to *hopefully* the next gear. Several pounds of rotating steel and aluminum are accelerating quickly towards *where* you want to shift. IF you miss, that right foot is still planted and if you're not running a 2-step...well...the stock tune has, as I recall, a neutral/park rpm limit somewhere well north of 6500 rpm, and even when that kicks in, that mass of rotating steel and aluminum that previously under a 4000 lb static, plus whatever aero load, are now free to spin much, much higher. Not a good scenario as Jannetty and TT pointed out to you earlier.

Exactly. For example, trying to shift from 2nd to 3rd, but getting it into 1st instead.

Nothing wrong with powershifting if you use proper shift technique, but with stock calibration the ETC will close the throttle blade when the clutch is depressed even if the gas pedal is on the floor. Isn't an issue with cable-driven throttle cars.

Ok so can this calibration be changed and is it normally changed in a custom tune? And will it improve et when powershifting at the dragstrip?

Yes, I got my tune. Don't really feel much difference with the torque management like people say, but I have a m6, not an automatic. Wot does feel a little bit stronger though. I also datalogged and didn't see any more knock retard, so I am pleased with that aspect. Thanks JRE
